PETER WALLING, OF SALEM, MASSACHUSETTS.

BRIDGE-GUARD.

SPECIFICATION forming part of Letters Patent No. 227,664, dated May 18,1880.

` Application ined March 22,1880. (No model.)

To all whom it may concern:

Be it known that I, PETER WALLING, o Salem, in the county of Essex,State of Massachusetts, have invented a cetain new and usefulImprovement in Bridge-Guards, 'of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which my invention.

appertains to make and use the same, reference being made to theaccompanying drawing, forming a part of this speciiication, in which thefigure is a view showing the guard in use.

My invention relates to that class of bridgegua-rds which are employedon railroads to prevent the train-men stationed on moving freight-trainsfrom receivinginjury by coming into contact with overhead bridges; andit consists in a novel construction and arrangement of parts, ashereinafter fully set forth and claimefhby which a simpler, cheaper, andmore effective device of this character is produced than is now inordinary use.

In the drawing, A represents the post or support, B the axle, and G thebar.

The axle is arranged in an inclined position at an angle of aboutforty-five degrees to the post A, being pivoted or journaled at itslower end in the step a, and at its upper end, at d, in the outer end ofthe bracket or brace m.

The bar C is arranged to extend horizontally over the track of therailroad, and has one of its ends firmly secured at z in the axle thusgive him timely warning ofthe approach ofthe train to the bridge.

The inclination of the axle B to the post A causes the bar C to swingwith a pendulous motion, or its outer end to be elevated, as

shown by the dotted lines, when the bar is moved in either directionfrom its lowest or proper position over the track, and to gravitate orreturn automatically to its proper position after having been moved orswung out of the same, thus readjusting itself, as will be readilyunderstood by all conversant with such matters without a more explicitdescription.

Having thus explained my invention, what I claim is- In an overheadbridge-guard, the combination of the post A, inclined axle B, andhorizontal bar C, arranged to operate substantially as and for thepurpose specified.

PETER WALLING.
